Question:Last year, I got an A on Algebra 1 and it was easy!! This year, I have Honors Geometry which is the first time I have an Honors class. But, Geometry just punched me in right of my face! It is tricky and have a lot of logical thinking! I got a C on the chapter 1 test. I learned that Algebra 1 and Geometry are opposite. I don't get it. How are they opposite? Please help me. How can I survive through Geometry. If I didn't well on the next test, I have to take regular Geometry class. Okay answer my questions
1. How Algebra 1 and Geometry are opposite?
2. Any advices for surviving through Geometry? (don't say practice)
3. How do you take a lot of logical thinking?
NO SILLY ANSWERS

Answers:1. I think because most people are either good at algebra, but struggle with geometry or they are good at geometry and they are good at algebra.
2. Well once you get into it you should find that it involves a lot of algebra. Just take good notes, listen in class, ask questions, and ask your teacher for extra help.

Question:1. Why did the Jewish leaders send representatives to find out who John was?
2. What do you think they wanted his answer to be?
3. Decribe in your own words Johns mission as he stated in verse 23.
4. Why did John call Jesus the "Lamb of God."
5. In what ways was Jesus like a Lamb?
I'll be surprised if you know at least 2-4 of these. This is not my homework Iam testing you and iam 22

Answers:Elijah, thats who they hoped he would be, a forerunner to the messiah, John came to help establish a new covenant. To teach people to start changing from the inside out, he came to teach them that the old way of sacrificing animals did not take away the guilt of sin and that a better way was coming, Jesus was Perfect, and as a lamb led to the slaughter he opened not his mouth and died the terrible death on the Cross as a Sacrifice for our sins. To take away the sins of the world, Praise and Glory to the Lamb!!!

Question:I am studying for a test and I have answered all the questions except for four. On these questions I need to name the variable.
1. the sum of the digits of a positive two-digit number is 13. if twice the first digit is 1 less than the second digit, what is the two-digit number?
2. How many ounces of a 20% salt solution should be mixed with a 10% salt solution to produce 45 ounces of a 14% salt solution?
3. With a tailwind, a jet flew 2000 miles in 4 hours, but the return trip against the same wind required 5 hours. Find the jet's speed and the wind speed.
4. A grocery store sells a mixture of peanuts and raisins for $1.75 per pound. If peanuts cost $1.25 per pound and raisins cost $2.75 per pound, what amount of raisins and peanuts go into 1 pound of the mixture?

Answers:1. the sum of the digits of a positive two-digit number
is 13. if twice the first digit is 1 less than the second
digit, what is the two-digit number?
I assume the first digit is the units digit. If it is not, change the variables
t=tens digit
u=units digit
t+u=13
2u+1=t
---
3u+1=13
u=4
t=9
94
===============================
2. How many ounces of a 20% salt solution should be
mixed with a 10% salt solution to produce 45 ounces
of a 14% salt solution?
x=amount of 20% solution
y=amount of 10% solution
x+y=45
.2x+.1y=.14(45)
.2x+.1(45-x)=.14(45)
.2x+4.5-.1x=6.3
.1x-1.8
x=18
y=27
18 ounces = amount of 20% solution
27 ounces = amount of 10% solution
==================================
3. With a tailwind, a jet flew 2000 miles in 4 hours,
but the return trip against the same wind required
5 hours. Find the jet's speed and the wind speed.
x=jet's speed
y=wind's speed
4(x+y)=2000---->x+y=500
5(x-y)=2000----->x-y=400
add
2x=900
x=450
y=50
450 mph=jet's speed
50 mph=wind's speed
=================================
4. A grocery store sells a mixture of peanuts and
raisins for $1.75 per pound. If peanuts cost $1.25 per
pound and raisins cost $2.75 per pound, what
amount of raisins and peanuts go into 1 pound of the
mixture?
r=raisins
p=peanuts
r+p=1
125p+275r=175(1)
125(1-r)+275r=175(1)
125-125r+275r=175
150r=50
r=1/3
1/3 pound of raisins
2/3 pound of peanuts

Question:I had a test today and there were three problems I wasn't sure of. Can you tell me the answers to these three please?
1. What is the geometric mean of 9 and 27. Answer in simplist radical form.
2. What is the geometric mean of 10 and 18. Answer in simplist radical form.
3. There is a right triangle with sides 13, 12, and 6. What is the length of the altitude from the right angle to the hypotenuse.
If you only know 1 of the answers, it is better than nothing. Plaese help. Thanks

Answers:3.
Area of this right triangle is 6*12/2=36
But the same area may be computed multiply hypotenusa with the length of the altitude from the right angle to the hypotenuse and divide by 2
then this length is 36*2/13
The real problem is : 13,12 and 6 are not form a right triangle.
because 12^2+6^2 is not equal with 13^2
